[0002] A LUMINAIRE

[0003] FIELD OF THE INVENTION

[0004] The present invention relates to the field of lighting, and in particular to linear luminaires.

[0005] BACKGROUND OF THE INVENTION

[0006] Artificial lighting products and systems are increasing in popularity as a solution for lighting or illuminating an environment. A popular luminaire usable for illuminating an environment is a linear luminaire.

[0007] One form of linear luminaire comprises a housing and a linear lighting module. The linear lighting module can be positioned and secured against the housing so that it lies flush to the housing. The housing is configured to permit coupling of the linear luminaire to an external surface, such as a ceiling, e.g., via one or more cables or other hanging elements.

[0008] For reduced environmental impact of artificial lighting products, there is an increasing focus upon reusability and repairability of luminaires. There is therefore a desire, for linear luminaires, for increased ease in removing or detaching the linear luminaire module from the housing.

[0009] US 2024271776A1 discloses a retrofit light emitting diode structure that includes a LED panel including at least a light emitting diode light source contained within an assembly or a lens and base housing.

[0010] WO 2024227621A1 discloses a luminaire comprises a luminaire housing, a light module and a torsion spring comprising a coil and a pair of legs extending from the coil.

[0011] CN 107842830A discloses an assembly structure of a lamp holder and a light bulb, which comprises a case, on which a light bulb is installed.

[0012] SUMMARY OF THE INVENTION

[0013] The invention is defined by the claims.

[0014] According to examples in accordance with an aspect of the invention, there is provided a luminaire comprising a lighting module configured to generate light, a housing configured to couple the luminaire to an external surface, and a module positioning mechanism 2024PF80313

[0015] 2 configured to moveably connect the lighting module to the housing. The module positioning mechanism is configured to move the lighting module between a first position, in which the lighting module sits flush against the housing, and a second position in which the lighting module is spaced apart from the housing.

[0016] In preferable examples, the luminaire may be a linear luminaire, and the lighting module may be a linear lighting module.

[0017] The proposed linear luminaire has a housing and a (linear) lighting module that are able to lie flush with one another. In particular, the lighting module is moveable, using a module positioning system, between a first position in which the housing and lighting module sit flush with one another and a second position in which the housing and lighting module are separated from one another.

[0018] In this way, the proposed linear luminaire design allows for moveable positioning of the lighting module relative to the housing. The first position (a flush position) provides reduces a risk of foreign material (e.g., dust or moisture) ingress into the housing, exposure of potentially hazardous or dangerous elements (e.g., exposure of electrical components) and / or unwanted light leakage from the housing. The second position (a spacedapart position) allows for access for maintenance and / or replacement of one or more components of the linear luminaire, e.g., one or more components of the linear lighting module.

[0019] The linear lighting module may be configured to emit light in a direction away from the housing.

[0020] In some embodiments, the module positioning mechanism comprises a first biasing mechanism configured to bias the linear lighting module to the first position. The biasing mechanism ensures the lighting module is reliably maintained in its flush position, to further reduce the risks outlined above. This approach also reduces a risk of unintended movement of the lighting module during expected operational factors, e.g., due to environmental vibration(s) or other minor disturbances.

[0021] In some embodiments, the linear lighting module comprises a module surface facing the housing, the housing comprises a housing surface facing the module surface, and the module positioning mechanism comprises a pin at least partially located between the housing surface and the module surface that, responsive to a manipulation by an individual, presses against the module surface or the housing surface so as to move the linear lighting module from the first position to the second position.

[0022] This pin-based mechanism provides a simple and intuitive way for a user to adjust the position of the lighting module. 2024PF80313

[0023] 3

[0024] In some embodiments, the manipulation is a movement of the pin in a direction perpendicular to the housing surface. The perpendicular movement of the pin simplifies the adjustment process, making it easy for users to operate the mechanism with minimal effort.

[0025] In some embodiments, the module positioning mechanism further comprises a second biasing mechanism configured to bias the pin away from the module surface. The use of the second biasing mechanism facilities improved ease of access to the pin and reduces a risk of unintentional movement of the pin, e.g., and therefore unintentional movement of the linear lighting module.

[0026] In some embodiments, the module positioning mechanism comprises a first bracket portion connected to the housing, wherein the first bracket portion comprises a bracket surface facing the housing surface, the pin comprises a first engagement surface facing the bracket surface, and the second biasing mechanism is connected between the bracket surface and the first engagement surface of the pin. By connecting the second biasing mechanism between the first bracket portion and the pin, this prevents the second biasing mechanism from biasing the linear lighting module away from the housing, thereby reducing a risk that the lighting module will unintentionally move to the second position.

[0027] In some embodiments, the second biasing mechanism is a spring. This approach provides a cost-effective and reliable solution for maintaining the pin's position.

[0028] In some embodiments, the housing comprises a pin aperture through which the pin is exposed when the linear lighting module is in the first position. The use of a pin aperture design allows for easy user access to the adjustment mechanism while maintaining a clean exterior appearance. More particularly, this embodiment enables users to quickly locate and operate the pin.

[0029] In some embodiments, the pin comprises a second engagement surface configured to engage with the housing surface of the housing when the linear lighting module is in the first position and disengage from the housing surface of the housing when the linear lighting module is in the second position. This dual-engagement surface design ensures secure positioning in both the flush and spaced-apart configurations.

[0030] In some embodiments, the module positioning mechanism comprises a release mechanism configured to switch between a hooked state, in which the linear lighting module is fixed to the housing, and a detached state, in which the linear lighting module is released from the housing. The release mechanism allows for easy removal of the lighting module for maintenance or replacement. 2024PF80313

[0031] 4

[0032] In some embodiments, the module positioning mechanism and linear lighting module are configured to, when the linear lighting module is in the first position, cover the release mechanism, and when the linear lighting module is in the second position, expose the release mechanism for permitting activation of the release mechanism. This configuration functions to reduce a risk of accidental activation of the release mechanism during normal operation, as well as providing a more compact luminaire when the lighting module is the first (flush) position to reduce a space occupied by the luminaire. This approach also prevents or reduces a risk of material ingress towards the release mechanism (i.e., as it will be covered during normal use), thereby reducing a risk of failure or breakage of the release mechanism.

[0033] In some embodiments, the release mechanism comprises a helical torsion spring comprising a helical portion, a first bar portion extending from one end of the helical portion and a second bar portion extending from another end of the helical portion, a spring engagement mechanism connected to the helical portion of the helical torsion spring and either the housing or the linear lighting module, and a second bracket portion connected to the housing or the linear lighting module comprising a bracket aperture configured to receive the first bar portion and the second bar portion therethrough. When the release mechanism is in the hooked state, the first bar portion and the second bar portion engage with bounds of the bracket aperture, and when the release mechanism is in the detached state, the first bar portion and second bar portion disengage with bounds of the bracket aperture to permit release of the linear lighting module from the housing.

[0034] This release mechanism design provides a secure connection in the hooked state while allowing for easy detachment of the linear lighting portion from the housing when needed.

[0035] In some embodiments, the first bar portion and the second bar portion each comprise a respective hook portion configured to: engage with the second bracket portion when the release mechanism is in the hooked state and the linear lighting module is a predetermined distance away from the housing; and be disengaged from the second bracket portion when the release mechanism is in the detached state. This approach is able to reduce a risk of accidental or unintentional detachment of the linear lighting module from the housing during normal operation or maintenance.

[0036] In some embodiments, the release mechanism is manually manipulable between the hooked state and the detached state. This provides a user with direct control over the attachment and detachment process, e.g., eliminating the need for specialized tools, simplifying maintenance procedures. 2024PF80313

[0037] 5

[0038] In some embodiments, the release mechanism is biased towards the hooked state. Biasing the release mechanism towards the hooked state ensures that the lighting module remains securely attached during normal operation. This design choice enhances safety and reliability, reducing a risk of unintended detachment due to vibrations or other minor disturbances.

[0039] In some embodiments, the housing comprises a first set of one or more projections and the linear lighting module comprises a second set of one or more projections. When the linear lighting module is in the first position, the first set of one or more projections engage with the second set of one or more projections so as to restrict movement of the linear lighting module beyond the first position, and when the linear lighting module moves from the first position to the second position, the first set of one or more projections disengage with the second set of one or more projections.

[0040] This projection-based design provides a mechanical stop to prevent over-travel of the lighting module when moving from the second position to the first position, i.e., to more specifically define the first position.

[0041] These and other aspects of the invention will be apparent from and elucidated with reference to the embodiment s) described hereinafter.

[0052] DETAILED DESCRIPTION OF THE EMBODIMENTS

[0053] The invention will be described with reference to the Figures.

[0054] It should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the apparatus, systems and methods, are intended for purposes of illustration only and are not intended to limit the scope of the invention. These and other features, aspects, and advantages of the apparatus, systems and methods of the present invention will become better understood from the following description, appended claims, and accompanying drawings. It should be understood that the Figures are merely schematic and are not drawn to scale. It should also be understood that the same reference numerals are used throughout the Figures to indicate the same or similar parts.

[0055] The invention provides a linear luminaire with a linear lighting module and a housing for receiving the linear lighting module. A module positioning mechanism of the linear luminaire moveably connects the linear lighting module to the housing. In particular, the module positioning mechanism is configured to facilitate movement of the linear lighting module between a first position and a second position. When in the first position, the linear lighting module and the housing sit flush with one another. When in the second position, the linear lighting module and the housing are distanced from one another.

[0056] In the context of the present disclosure, a "linear luminaire" is a lighting fixture or device (i.e., a luminaire) having an elongated form. In particular, a linear luminaire may have a length that is substantially greater (e.g., more than 5 times greater) than its width or height. Linear luminaires may have various cross-sectional shapes, such as rectangular, square, circular, or oval, while maintaining their elongated profile, as would be readily apparent to the skilled person.

[0057] Figures 1, 2, 3 and 4 each illustrate a portion of a proposed linear luminaire 100. The linear luminaire comprises a linear lighting module 110 and a housing 120. The linear lighting module 110 is configured to generate light, e.g., in a direction away from the housing 120 when the linear luminaire 100 is assembled.

[0058] In particular, the linear lighting module may comprise one or more lighting elements (not visible in Figures 1, 2, 3 or 4) and a light output surface 199, e.g., formed of a 2024PF80313

[0059] 7 non-opaque material such as glass or plastic. The lighting elements are configured to generate light that is output from the light output surface.

[0060] The housing 120 is configured to couple the linear luminaire 100 to an external surface (not visible in Figures 1, 2, 3 or 4), such as a ceiling or wall. Accordingly, the housing may comprise one or more coupling elements 129 for engaging the linear luminaire 100 to the external surface, e.g., via one or more mechanical coupling mechanisms.

[0061] In some examples, the housing 120 is configured to bound a volume for receiving the linear lighting module. Thus, the volume bound by the housing may be suitably sized to receive therein the linear lighting module.

[0062] In the illustrated example, the housing 120 is formed from an elongated structure defining a space or aperture for receiving the linear lighting module therein. In particular, two side walls 127A (of which only one is visible in Figures 1, 2 and 4) extend parallel to one another, with a space between the two side walls defining a region into which the linear lighting module is receivable.

[0063] The linear luminaire 100 further comprises a module positioning mechanism 130 configured to moveably connect the linear lighting module 110 to the housing 120. More particularly, the module positioning mechanism is configured to move the linear lighting module 110 between a first position (Figure 1) and a second position (Figures 2, 3 and 4).

[0064] When the linear lighting module 110 is in the first position, the linear lighting module sits flush against the housing 120.

[0065] More particularly, the light output surface 199 of the linear lighting module 110 may sit flush against the housing 120 when the linear lighting module 110 is in the first position. Even more particularly, when the linear lighting module 110 is in the first position, a plane in which the light output surface 199 of the linear lighting module lies may abut the housing 120. Even more particularly, when the linear lighting module 110 is in the first position, a volume bound by the housing may contain an entirety of the linear lighting module. Even more particularly, when the linear lighting module 110 is in the first position, the linear lighting module may abut an edge of the volume bound by the housing, e.g., and not extend outside of the volume bound by the housing, such that the linear lighting module lies flush with the housing.

[0066] More particularly, the two side wall(s) 127 A of the housing 120 extend to a plane on which (e.g., the light output surface 199 of) the linear lighting module is positioned. Put another way, the two side walls 127A of the housing and the linear lighting module may 2024PF80313

[0067] 8 lie flush against a same plane. In this way, the light output surface 199 is flush with the side walls of the housing 120.

[0068] This flush arrangement between the linear lighting module 110 and the housing 120 helps protect the internal components of the linear lighting module 110 from dust, debris, or other environmental factors.

[0069] When the linear lighting module is in the second position, the linear lighting module 110 is spaced apart from the housing 120, i.e., there is a non-zero gap between the linear lighting module and the housing 120. This spaced-apart configuration facilitates at least access to the internal components of the linear luminaire 100, facilitating maintenance, repair, or replacement of parts.

[0070] In some examples, the module positioning mechanism 130 comprises a first biasing mechanism 135 configured to bias the linear lighting module 110 to the first position.

[0071] By way of example, as illustrated in Figures 1 and 2, the first biasing mechanism 135 may comprise a spring element (here: a torsion spring, but alternatively a coil spring, leaf spring). The spring element is connected between the housing 120 and the linear lighting module 110 to exert a biasing force that urges the linear lighting module 110 towards the first position (Figure 1) where it sits flush against the housing 120.

[0072] More specifically, in the illustrated example, the first biasing mechanism 135 comprises a helical torsion spring 140 comprising a helical portion 141, a first bar portion 142 extending from one end of the helical portion and a second bar portion 143 extending from another end of the helical portion.

[0073] The first 142 and second 143 bar portions are configured to press against a first bracket portion 161 connected to either the housing 120 or the linear lighting module 110 (in the illustrated example: the housing 120). The helical portion is secured to the other of the housing 120 and the linear lighting module 110 (in the illustrated example: the linear lighting module 110). In this way, the bracket (and therefore the housing or linear lighting module) is pulled towards the other one of the housing and linear lighting module.

[0074] As another simple example, the first biasing mechanism may comprise a helical / coil spring connected between the housing and the linear lighting module. The helical / coil spring may be configured to exert a biasing force that urges the linear lighting module towards the first position where it sits flush against the housing.

[0075] The module positioning mechanism 130 may comprise a pin 150 for moving the linear lighting module between the first and second positions. More particularly, the linear lighting module 110 may have a module surface 111 facing the housing, while the housing 2024PF80313

[0076] 9 may have a housing surface 121 facing the module surface. The pin 150 is least partially located between these two surfaces.

[0077] When an individual manipulates the pin 150, the pin 150 is configured to press against either the module surface 111 or the housing surface 121. In other words, the pin 150 is configured to press against the module surface 111 or the housing surface 121 responsive to a manipulation by the individual. This pressing causes the linear lighting module 110 to move from the first position to the second position.

[0078] More particularly, it will be appreciated that the manipulation of the pin 150 may be in a direction DI perpendicular to the housing surface 121, e.g., away from the housing surface or away from the module surface. In this way, the module surface I l l is pushed away from the housing surface 121 or vice versa, to thereby move the linear lighting module from the first position to the second position.

[0079] Put another way, when the pin 150 is moved from a first pin position (Figure 1) to a second pin position (Figure 2), the pin presses against the module surface 111 or the housing surface to thereby move the linear lighting module from the first position to the second position.

[0080] In some examples, the manipulation of the pin 150 to move the linear lighting module from the first position to the second position is preferably a movement of the pin in a first pin direction DI .

[0081] In the illustrated example, the first pin direction DI is a direction from the housing surface 121 to the module surface 111. In this way, when moved in the first pin direction, the pin 150 presses against the module surface 111 so as to move the linear lighting module away from the housing 120 (i.e., move the linear lighting module from the first position to the second position).

[0082] However, in other examples, the first pin direction is from the module surface to the housing surface. In such examples, when moved in the first pin direction, the pin may press against the housing surface so as to move the linear lighting module away from the housing.

[0083] The pin 150 may be accessible or exposed through / via an aperture in the housing or the linear lighting module when the linear lighting module is in the first position.

[0084] In the illustrated example, the housing 120 comprises a comprises a pin aperture 125 through which the pin is exposed when the linear lighting module is in the first position. This provides pin access for an individual to manipulate (e.g., press against) the pin in order to move the linear lighting module towards the second position. 2024PF80313

[0085] 10

[0086] More particularly, when the pin 150 is in the first pin position (and the linear lighting module is in the first position), the pin may be exposed outside of the housing 120. When the pin is in the second pin position (and the linear lighting module is in the second position) the pin is no longer exposed outside of the housing 120.

[0087] However, in other examples, the pin is accessible through an aperture in the linear lighting module. In such examples, the pin may be exposed outside of the linear lighting module when in the first pin position, and may no longer be exposed outside of the linear lighting module when in the second pin position. This configuration is usable, for instance, when the pin is configured to (when manipulated by the user) press against the housing surface to move the linear lighting module 110 to the second position.

[0088] In some examples, the module positioning mechanism 130 further comprises a second biasing mechanism 155 configured to bias the pin to the first pin position. For instance, in the illustrated example, the second biasing mechanism is configured to bias the pin away from the module surface 111.

[0089] In particular, the second biasing mechanism 155 is positioned between the pin 150 and a fixed point on or connected to the housing 120 or linear lighting module 110. The second biasing mechanism 155 may exert a force on the pin 150 to bias the pin towards the first pin position, e.g., in a direction away from the module surface 111 or the housing surface 121 (as appropriate) against which the pin is configured to press to move the linear lighting module 110 to the second position.

[0090] The second biasing mechanism serves to maintain the pin 150 in the first pin position when the linear lighting module 110 is in the first position, to thereby facilitate access to the pin by a user for ease of manipulating the pin.

[0091] The second biasing mechanism 155 may, for instance, be a spring, such as a spring wrapped around a portion of the pin 150 (for improved compactness of the linear luminaire). However, in other examples, the second biasing mechanism may be embodied as resilient piece of material such as rubber.

[0092] In the illustrated example, the module positioning mechanism comprises a first bracket portion 161 connected / mounted (e.g., directly) to the housing 120. The first bracket portion 161 comprises a bracket surface 164 facing the housing surface 121. The pin 150 comprises a first engagement surface 151 facing the bracket surface. The second biasing mechanism 155 is connected between the bracket surface and the first engagement surface of the pin. In this way, the second biasing mechanism presses the first engagement surface 151 2024PF80313

[0093] 11 away from the bracket surface and towards the housing surface, thereby biasing the pin to the first position.

[0094] As previously explained, in the illustrated example, the pin 150 pushes against the module surface 111 (responsive to a user manipulation) to move the linear lighting module to the second position. By positioning the second biasing mechanism 155 between the first bracket portion 161 and the housing 120, the second biasing mechanism does not push against the linear lighting module 110, thereby reducing a risk that the linear lighting module 110 will unintentionally move to the second position.

[0095] In other examples, such as when the pin is configured to push against the housing surface to move the linear lighting module to the second position, the first bracket portion may instead be connected / mounted (e.g., directly) to the housing 120. In such examples, the second biasing mechanism may be positioned between the first bracket portion and the linear lighting module, thereby reducing the risk of unintentional movement of the linear lighting module to the second position.

[0096] In some examples, the pin 150 comprises a second engagement surface 152 configured to engage with one of the housing surface 121 and the module surface 111 when the linear lighting module is in the first position and disengage from said one of the housing surface and the module surface 111 when the linear lighting module is in the second position.

[0097] In particular, in embodiments where (responsive to a user manipulation) the pin contacts the module surface 111 to push the linear lighting module to the second lighting position, the second engagement surface 152 contacts the bousing surface 121 when the linear lighting module is in the first position. Similarly, in embodiments where the pin contacts the housing surface to push the linear lighting module to the second position, the second engagement surface contacts the module surface when the linear lighting module is in the first position.

[0098] These approaches act to restrict a maximum movement of the pin, e.g., to prevent the pin from ejecting or being unintentionally removed from the linear luminaire. In other words, the second engagement surface 152 functions as a physical stop that limits travel of the pin within the housing or linear lighting module.

[0099] Even more particularly, in embodiments in which the pin passes through an aperture 125, the aperture may be designed with a slightly smaller diameter than the widest part of the pin, creating an interference fit that helps retain the pin while still allowing for intended movement. 2024PF80313

[0100] 12

[0101] The module position mechanism 130 may further comprise a release mechanism 140, 180, 162. The release mechanism is configured to switch between a hooked state (Figures 1, 2 and 3) and a detached state (Figure 4). The switching between the hooked state and the detached state is preferably user controllable, e.g., manipulated by a user accessing the release mechanism.

[0102] When the release mechanism is in the attached state, the linear lighting module is fixed to the housing. When the release mechanism is in the detached state, the linear lighting module is released from the housing. In other words, the linear lighting module is disengaged from the housing. This disengagement allows for the separation of the linear lighting module from the housing, facilitating access for maintenance or replacement of one or more elements of the linear lighting module (e.g., replacement of the entire linear luminaire module).

[0103] More particularly, the module positioning mechanism and linear lighting module may be configured to, when the linear lighting module is in the first position, cover the release mechanism. In this way, access to the release mechanism is prevented when the linear lighting module is in the first position.

[0104] In some examples, when the linear lighting module is in the second position, the module positioning mechanism and linear lighting module are configured to expose the release mechanism for permitting activation of the release mechanism. In other words, access to the release mechanism is permitted when the linear lighting module is in the second position.

[0105] In the illustrated example, the release mechanism comprises a helical torsion spring 140 with a helical portion 141, a first bar portion 142 extending from one end of the helical portion, and a second bar portion 143 extending from another end of the helical portion.

[0106] The illustrated release mechanism also includes a spring engagement mechanism 180 connected to the helical portion of the helical torsion spring and either the housing or the linear lighting module. Additionally, the illustrated release mechanism comprises a second bracket portion 162 may be connected to the housing or the linear lighting module, comprising a bracket aperture 165 configured to receive the first bar portion and the second bar portion therethrough.

[0107] When the release mechanism is in the hooked state (Figure 2), the first bar portion 142 and the second bar portion 143 engage with bounds of the bracket aperture 165. In other words, the first bar portion 142 and the second bar portion 143 hook onto the second bracket portion 162 when the release mechanism is in the hooked state. In particular, the helical portion 141 of the helical torsion spring 140 will press the bar portions 142, 143 against the bounds of the bracket aperture. 2024PF80313

[0108] 13

[0109] Conversely, when the release mechanism is in the detached state (Figure 4), the first bar portion 142 and second bar portion 143 disengage with the bounds of the bracket aperture to permit release of the linear lighting module from the housing. More particularly, the first bar portion 142 and the second bar portion 143 no longer hook onto the second bracket portion 162 when the release mechanism is in the detached state, allowing passage of the bar portions 142, 143 through the bracket aperture 165 and release of the linear lighting module 110 from the housing 120.

[0110] In some examples, the release mechanism may be manually manipulable between the hooked state and the detached state. This can be achieved through appropriate sizing of the bar portion 141, 142 (i.e., to permit manual manipulation of the position of the first and second bar portions when the linear lighting module is in the second position) and / or the strength of biasing performed by the helical torsion spring (to permit manual movement of the first and second bar portions). This approach facilitates user control over the attachment and detachment of the linear lighting module from the housing.

[0111] More specifically, movement of the release mechanism from the hooked state to the detached state can be achieved by (manually) squeezing the first bar portion 142 and the second bar portion 143 together, before pulling or extracting both bar portions 142, 143 through the bracket aperture 165. The process can be reversed to move the release mechanism from the detached state to the hooked state, e.g., by (manually) squeezing the first bar portion 142 and the second bar portion 143 together before pushing both bar portions 142, 143 through the bracket aperture 165, after which the bar portions may be released so that the helical torsion spring 141 biases them to engage with the bounds of the bracket aperture 165.

[0112] The first bar portion 142 and the second bar portion 143 may each comprise a hook portion 145, 146 for engaging with the bracket aperture 165. In particular, the first bar portion 142 may comprise a first hook portion 145 and the second bar portion 143 may comprise a second hook portion 146. This reduces a likelihood that the release mechanism will unintentionally move to the detached state.

[0113] In particular, the hook portions 145, 146 may be configured to prevent the release mechanism from moving from the hooked state to the detached state within squeezing of the first bar portion 142 and the second bar portion 143 together.

[0114] Figure 3 more clearly illustrates the function of the hook portions 145, 146. In particular, when the release mechanism is in the hooked state, the hook portions 145, 146 of the first bar portion 142 and the second bar portion 143 are configured to engage with the second bracket portion 162 when the linear lighting module 110 is moved a predetermined 2024PF80313

[0115] 14 distance away from the housing 120. Thus, the engagement of the hook portions 145, 146 with the bounds of the bracket aperture 165 creates a mechanical interlock. This interlock resists any unintended separation forces that may occur during use or maintenance of the linear luminaire when the release mechanism is in the hooked state.

[0116] The use of the hook portions thereby prevents further movement of the linear lighting module 110 with respect to the housing 120 when the release mechanism is in the hooked state. This configuration helps to protect any internal wires and electrical connections from being snapped, e.g., due to yanking of the linear lighting module 110 before any such electrical connections have been safely detached.

[0117] In the illustrated approach, the movement from the hooked state to the detached state is achieved by manually squeezing or pressing (e.g., indicated by a squeezing action 350) the first bar portion 142 and the second bar portion 143 together. This deliberate manipulation overcomes the inherent tension of the helical torsion spring and disengages the hook portions from the bracket aperture 165.

[0118] More particularly, the squeezing action moves the hook portions to a position at which they are able to pass through the bracket aperture 165 (when the linear lighting module 110 is moved away from the housing 120) rather than engaging with the bracket aperture 165. Thus, the disengagement of the hook portion(s) from the bounds of the bracket aperture permits their passage through the bracket aperture to move the release mechanism to the detached state.

[0119] The requirement for a squeezing action adds an extra layer of security to the release mechanism by preventing or reducing a risk of accidental detachment due to vibrations, impacts, or other environmental factors. Only when an intentional, coordinated squeezing action is applied can the hook portions be maneuvered to allow their passage through the bracket aperture. In this way, the hook portions 145, 146 serve as a useful safety feature in the release mechanism design, by preventing accidental or unintentional detachment of the linear lighting module 110 from the housing 120 by requiring a deliberate action to disengage.

[0120] In this way, each hook portion functions as a stopper to restrict the movement of the linear lighting module 110 away from the housing 120 whilst the release mechanism is in the hooked state.

[0121] In some examples, if both a first bracket portion 161 and second bracket portion 162 are used, the first bracket portion and the second bracket portion may be formed from the same component, i.e., form portions of a same bracket 160. This (combined / integrated) bracket thereby serves a dual function within the linear luminaire. This integrated bracket design simplifies the overall structure and reduces the number of parts required. 2024PF80313

[0122] 15

[0123] In some examples, if both are used, the first biasing mechanism and the release mechanism of the module positioning mechanism 130 may be formed from the same component s), e.g., to simplify the design and reduce the number of parts in the linear luminaire. This integration may be achieved by making use of a single helical torsion spring 140 that serves both functions.

[0124] As previously explained, the helical torsion spring 140 may comprise a helical portion 141, a first bar portion 142 extending from one end of the helical portion, and a second bar portion 143 extending from another end of the helical portion.

[0125] When the linear lighting module 110 is in the first position (flush against the housing), the helical portion of the spring 141 may exert a biasing force that urges the linear lighting module towards the housing, thereby functioning as the first biasing mechanism. This biasing force may be applied through the first and second bar portions, which may engage with a bracket 162 or other structural element of the housing or linear lighting module.

[0126] Simultaneously, the first 142 and second 143 bar portions may be configured to engage with the bounds of a bracket aperture, i.e., functioning as the release mechanism in the hooked state, securing the linear lighting module 110 to the housing 120.

[0127] When the linear lighting module 110 is moved to the second position (by the module positioning mechanism 130), the bar portions are exposed to permit manual manipulation to be applied to squeeze the first and second bar portions together. In the second position, the first and second bar portions continue to exert a biasing force that urges the linear lighting module towards the housing whilst remaining engaged with the bounds of the bracket aperture. However, once squeezed and extracted from the bracket aperture, the release mechanism is switched to the detached state, allowing the linear lighting module to be separated from the housing.

[0128] By making use of this dual-function helical torsion spring, both the biasing function (to maintain the first / flush position of the linear lighting module) and the release mechanism function is achieved with a single component arrangement.

[0129] In some examples, the housing 120 may comprise a first set 126 of one or more projections, and the linear lighting module 110 may comprise a second set 116, 117 of one or more projections. When the linear lighting module is in the first position, the first set of one or more projections may engage with the second set of one or more projections so as to restrict movement of the linear lighting module beyond the first position. This engagement may help maintain the flush positioning of the linear lighting module against the housing. More particularly, the engagement between the first and second sets of one or more projections 2024PF80313

[0130] 16 function as a physical stop to restrict movement of the linear lighting module beyond the first position, preventing over-travel and potential damage to the components.

[0131] When the linear lighting module moves from the first position to the second position, the first set of one or more projections may disengage with the second set of one or more projections.

[0132] Each projection may may be shaped as a respective tab, ridge, or protrusion extending from one or more surfaces of the housing and linear lighting module.

[0133] In some examples, one or more the projections (e.g., the second set of projection(s)) may be designed with a slight taper to facilitate easier engagement and disengagement. More particularly, the taper may help guide the projections into place as the linear lighting module is moved into the first position. The side of the taper(s) may press against the side wall(s) 127A of the housing when the linear lighting module is in the first position, to improve the connection between the housing and the linear lighting module. The taper (if present) may be a taper that causes the projection to thin with increasing distance from the (remainder of the) linear lighting module.

[0134] It will be appreciated that the number and arrangement of projections may vary depending on the size and design of the linear luminaire. For longer luminaires, multiple sets of projections may be spaced along the length to provide consistent engagement and support.

[0135] Figure 5 provides an alternative view of a proposed linear luminaire 100 when the linear lighting module 110 is in the first position.

[0136] As illustrated in Figure 5, the housing 120 may comprise a pair of side walls 127 A, 127B between which the linear lighting module lies when in the first position.

[0137] In particular, Figure 5 better illustrates how the linear lighting module 110 sits flush with the housing 120 when the linear lighting module 110 is in the first position. More particularly, the linear lighting module 110 sits on a same plane Pl to which the side walls 127A, 127B of the housing extend. In this way, the light output surface 199 may be substantially coplanar with the side walls of the housing when the linear lighting module is in the first position.

[0138] Figure 5 also more clearly illustrates the optional taper (shape) of the second set of one or more projections.

[0139] Figures 6 and 7 each provide a respective exploded view of the proposed linear luminaire 100. 2024PF80313

[0140] 17

[0141] As previously explained, the housing 120 of the linear luminaire 100 is configured for mounting or coupling the linear luminaire 100 to an external surface (e.g., a ceiling or similar).

[0142] In the illustrated example, the housing 120 comprises an engagement surface 600. The engagement surface 600 is configured to interface with one or more mounting elements 610 for connecting the housing 120 (and therefore the linear luminaire) to the external surface.

[0143] The engagement surface 600 may be to facilitate secure and adjustable mounting of the linear luminaire 100 to different types of external surfaces. For example, the engagement surface 600 may include a set of one or more grooves, channels, or slots to allow for flexible positioning of the mounting elements 610. More particularly, the engagement surface may define one or more hooking surfaces against which a hooking element of the mounting element(s) is configured to hook. Thus , the engagement surface 600 may have appropriately designed attachment points or hooks to securely connect the mounting element(s) thereto.

[0144] Correspondingly, the structure and / or form of the mounting element(s) 610 may be variously configured dependent, for instance, upon the specific mounting needs and the nature of the external surface. In some examples, as illustrated, the mounting element(s) 610 may comprise one or more hooks for hooking onto a hooking surface of the engagement surface 600, e.g., at one or more points along its length.

[0145] In the illustrated example, the mounting element(s) 610 include one or more suspension cables or wires 612 for hanging the linear luminaire 100 from a ceiling. The engagement surface 600 may have specially designed attachment points or hooks to securely connect these suspension elements.

[0146] In some approaches, the mounting elements 610 may be designed to be partially or fully concealed within the housing 120 when the linear luminaire 100 is installed. This may be achieved by configuring the engagement surface 600 of the housing 120 to have one or more recesses that allow the mounting elements 610 to be at least partially covered by the housing 120.

[0147] The linear luminaire 100 may further comprise one or more end caps 620. Each end cap is configured to connect to the housing 120 to cover an exposed end of the housing 120. 2024PF80313

[0148] 18

[0149] The end cap(s) function to improve ingress protection of the linear luminaire 100. For instance, the end cap(s) function to reduce a risk of the ingress of dust, moisture, or other contaminants into the housing 120.

[0150] Figure 8 illustrates an assembled view of the proposed luminaire 100 for improved contextual understanding. The linear lighting module 110 is in the first position, and the (optional) end caps 620 are connected to the housing 120.

[0151] While the preceding description has focused on a linear luminaire with only a single module positioning mechanism, it will be appreciated that the linear luminaire may, in practice, comprise multiple module positioning mechanisms. Thus, the linear luminaire may comprise two or more module positioning mechanisms spaced along the length of the linear lighting module and housing. This configuration may provide more uniform support and movement of the linear lighting module, particularly for longer luminaires.

[0152] In such examples, each module positioning mechanism may be identical in design and function. Alternatively, they may be varied to suit different requirements along the length of the linear luminaire. For example, a first module positioning mechanism may comprise the release mechanism and the pin (for facilitating movement of the linear lighting module from the first position to the second position), whilst a second module positioning mechanism may comprise only the release mechanism. Other variants will be readily apparent to the skilled person.

[0153] In some cases, the use of multiple module positioning mechanisms may allow for sectional or position-specific movement of the linear lighting module. This could facilitate partial access to specific areas of the luminaire for targeted maintenance or repairs without needing to fully detach the entire linear lighting module from the housing.

[0154] The skilled person will appreciate that the number and placement / positioning of module positioning mechanisms may be dependent upon one or more characteristics of the linear luminaire (such as the length and weight of the linear lighting module, the desired level of support and stability and so on).

[0155] Ordinal numbers (e.g. “first”, “second” and so on) have been used purely to distinguish different elements from one another for the sake of clarity, and does not necessarily imply a specific order, importance, relationship, or presence of all numbered elements. Reference to a non-“firsf ’ (e.g. “second” or “third”) element does not necessitate that a “first” element be present. The skilled person would be capable of relabeling any such elements as appropriate (e.g. relabeling a “second” element as a “first” element if only the second element is present). 2024PF80313
